Hello,
I've got this splat after a couple of suspend-resume cycles on my

Pasting some logs before the actual WARN_ON, as they may be relevant.
Just after the splat the connection is successfully reestablished.

This seems to be a DVM device (iwldvm). What is the exact device
model? And you have never noticed this problem before?
Unfortunately this is a very old device and we don't support it
actively anymore. Hopefully this will turn out to be a trivial fix in
the driver side, so we can get it solved for you.
The best way to track this is to report it in
https://bugzilla.kernel.org.
